Updating the `link` function to target a specific DOM element within an Angular 2 component

Angular 1 uses the link function in a directive to target DOM elements.

link: function (scope, element, attr) {
    // do something with element[0], e.g. put generated graphics
    // inside the node
}

What is the equivalent feature in Angular 2?

Answer №1

Here's a solution that may fit your needs:

@Component({ 
...,
  template: `
  <div #target></div>
`
})
class CustomComponent {
  @ViewChild('target') target;

  // This function is triggered when `this.target` is ready to be used
  ngAfterViewInit() {
    var graphVisual = new vis.Graph2d(
        this.target.nativeElement, data, config);
  }
}
